蔬菜中农残去除方法研究

以萝卜和菠菜为样品,采用正交试验,研究了不同方法组合对蔬菜中农残的去除效果.结果表明,去除根茎类蔬菜农残的方法组合为2%洗涤剂浸泡10min后,用自来水漂洗3次,每次1min后,再用沸水烫漂1min;去除叶菜类蔬菜农残的方法优化组合为2%洗涤剂浸泡15min后,用自来水漂洗2次,每次1min后,再用沸水烫漂1min.     

Review:Assessing potential dietary toxicity of heavy metals in selected vegetables and food crops

INTRODUCTION Regulation, handling and bioremediation of hazardous materials require an assessment of the risk to some living species other than human being, or assessment of hazard to the entire ecosystem. As- sessment endpoints are values of the ecosystem that are to be protected and are identified early in the analysis. Such endpoints may include life cycle stages of a species and reproductive or growth patterns. Ecosystem risk assessment is at its dawn with this area of environment sci…

微波消解石墨炉原子吸收法测定蔬菜中的痕量镉

采用微波消化技术，以自吸背景校正方式，在硝酸介质中，NH4H2PO4和Mg(NO3)2混合物为基体改进剂，直接用石墨炉原子吸收法测定了蔬菜中的镉，并研究了最佳的实验条件．该法在0-6μg／L范围内呈良好的线性关系，检出限为0．16μg／L，回收率为96．4％-103．8oA．用于蔬菜中痕量镉的测定，结果满意。     

Identification of technology options for reducing nitrogen pollution in cropping systems of Pujiang

This work analyses the potential role of nitrogen pollution technology of crop systems of Pujiang, County in Eastern China‘s Zhejiang Province, rice and vegetables are important cropping systems. We used a case study approach involving comparison of farmer practices and improved technologies. This approach allows assessing the impact of technology on pollution, is forward looking, and can yield information on the potential of on-the-shelf technology and provide opportunities for technology development. The approach particularly suits newly developed rice technologies with large potential of reducing nitrogen pollution and for future rice and vegetables technologies. The results showed that substantial reductions in nitrogen pollution are feasible for both types of crops.
